Over at First Things, Princeton professor Robert P. George highlights these candid comments (emphasis added) from a leading lesbian activist:

It’s a no-brainer that (homosexuals) should have the right to marry, but I also think equally that it’s a no-brainer that the institution of marriage should not exist. . . . Fighting for gay marriage generally involves lying about what we are going to do with marriage when we get there—because we lie that the institution of marriage is not going to change, and that is a lie.

The institution of marriage is going to change, and it should change. And again, I don’t think it should exist. And I don’t like taking part in creating fictions about my life. That’s sort of not what I had in mind when I came out thirty years ago.

I have three kids who have five parents, more or less, and I don’t see why they shouldn’t have five parents legally. . . . I met my new partner, and she had just had a baby, and that baby’s biological father is my brother, and my daughter’s biological father is a man who lives in Russia, and my adopted son also considers him his father. So the five parents break down into two groups of three. . . . And really, I would like to live in a legal system that is capable of reflecting that reality, and I don’t think that’s compatible with the institution of marriage.

Professor George continues: “It is no longer uncommon for advocates of redefining marriage to acknowledge that the effect—for them an entirely desirable effect—of redefinition will be the radical transformation of the institution,” including “undermin[ing] its structuring norms of monogamy [and] exclusivity.” Somehow those acknowledgments receive little attention in the public debate over marriage.
